摘要

The hydrocode simulations were conducted to verify the JEM Pressurized Module shield and structural performance for the orbital debris impacts to complement the HVI test capabilities. The first part reports the design evaluation for the strikes of debris smaller than 1 cm in diameter. The simulation results are correlated with the HVI test results and agreed well in the middle-velocity range of 3 to 6 km/sec .However, the simulation results in the high-velocity range of 8 to 14 km/sec where the HVI test data is not available show lower ballistic performance than the empirical ballistic limit curve given by Christiansen. Nex, we report the results of hydrocode simulation results for large (5 and 10 cm in diameter) debris impacts with a velocity of 14km/sec. The simulations were conducted to estimate the module wall penetration hole size to be used for the follow-on structural safety assessments.
